At its greatest extent in the 13th and 14th centuries, the Mongol Empire stretched from northeastern Europe to northern China and the Pacific, and this well-written set covers its entire history, from founding to expansion and enormous influence to decline… The Mongol empire is an often overlooked part of history, and this set gives it the attention it deserves. VERDICT A first purchase for middle school and early high school students.
